URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 268 NWS Storm Prediction Center Norman OK 645 PM EDT Fri May 16 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northeast Illinois Northern Indiana Far Northwest Ohio * Effective this Friday night from 645 PM until Midnight EDT. * Primary threats include... Scattered damaging wind gusts to 70 mph possible Isolated large hail events to 1.5 inches in diameter possible SUMMARY...High-based thunderstorms should pose a threat for mainly severe/damaging winds through the evening. Peak gusts may reach up to 60-70 mph. The severe thunderstorm watch area is approximately along and 100 statute miles east and west of a line from 60 miles west northwest of Fort Wayne IN to 85 miles west southwest of Fort Wayne IN. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area.

MD 0818 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR NORTHEAST WI INTO CENTRAL UPPER MI
Mesoscale Discussion 0818 NWS Storm Prediction Center Norman OK 0230 PM CDT Fri May 16 2025 Areas affected...northeast WI into central Upper MI Concerning...Severe potential...Watch unlikely Valid 161930Z - 162130Z Probability of Watch Issuance...20 percent SUMMARY...Isolated severe gusts with small to marginally severe hail will be possible into early evening with high-based thunderstorms advancing north-northeast from northeast Wisconsin into central Upper Michigan. DISCUSSION...Scattered high-based thunderstorms have developed downstream of the vertically stacked cyclone over northern MN. Despite surface dew points only in the 40s to low 50s, storm development has been sustained where temperatures warmed into the low to mid 80s. This has yielded a deep inverted-v thermodynamic profile. Shear within the buoyancy layer appears weak, but the steep lapse rates through the troposphere will foster small to marginally severe hail cores. This should enhance downdrafts and could support strong to severe microbursts as convection spreads northeast through the rest of the afternoon. ..Grams/Mosier.. 05/16/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0819 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR MUCH OF NORTHEAST TEXAS INTO MUCH OF SOUTHERN ARKANSAS
Mesoscale Discussion 0819 NWS Storm Prediction Center Norman OK 0310 PM CDT Fri May 16 2025 Areas affected...much of northeast Texas into much of southern Arkansas Concerning...Severe potential...Watch likely Valid 162010Z - 162215Z Probability of Watch Issuance...80 percent SUMMARY...Scattered severe storms appear likely later this afternoon, with large hail and locally damaging gusts the most likely threats. DISCUSSION...The primary surface front currently extends from near Ft. Smith AR southwestward into parts of North Texas, with very strong instability in place. A special 19Z FWD sounding shows MLCAPE of 3250 J/kg, along with 0-6 km shear around 55 kt. Weak convergence along the front and continued heating should result in sporadic storm development along this boundary, and the environment will supercells producing very large hail. Visible imagery shows towering CU along portions of the front, and initiation appears likely in the next couple hours. ..Jewell/Mosier.. 05/16/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 0820 CONCERNING SEVERE THUNDERSTORM WATCH 263... FOR WESTERN/CENTRAL PA TO NORTHERN VA
Mesoscale Discussion 0820 NWS Storm Prediction Center Norman OK 0314 PM CDT Fri May 16 2025 Areas affected...western/central PA to northern VA Concerning...Severe Thunderstorm Watch 263... Valid 162014Z - 162215Z The severe weather threat for Severe Thunderstorm Watch 263 continues. SUMMARY...A mix of damaging winds and severe hail remains possible through early evening from western to central Pennsylvania southward into northern Virginia. A corridor of greater damaging wind potential is apparent in central Maryland, the District of Columbia, and far northern Virginia. DISCUSSION...Thunderstorm coverage has steadily increased ahead of a minor MCV, and separately along a wavy outflow boundary. Measured strong to severe wind gusts have occurred along the outflow associated with the MCV. Very strong mid-level winds persist in the wake of this MCV, as sampled by recent RLX VWP data. With surface temperatures in the mid to upper 80s ahead of this outflow, yielding peak MLCAPE of 2000-2500 J/kg, damaging wind swaths are most probable into central MD to far northern VA. Farther north, convection has largely struggled, outside of a slow-moving supercell along the separate outflow boundary in south-central PA. Mixed severe hail and damaging wind will remain possible here, amid weak low-level shear/SRH. ..Grams.. 05/16/2025 ...Please see www.spc.noaa.gov for graphic product...
